can someone help my samsung gear won`t turn on, I tried charging it . can someone just help?!?

[AC Question]

i had a trip and i took the gear with me, the trip was to an hotel, so i would put it on charge when i go to sleep . the trip was 3 days. after a long while, I came to use my gear, as I was studying and did not have time for it, so at that time i went to check it, but surprise, surprise, it won`t work. it used to work 3 weeks ago but now its blocked. I tried changing the charger cable and the battery sign just popped out and i left it there for like, 2 days, i came for it in the morning and pressed the power button, still nothing.
I hope I can turn my gear back on.
